Physical aggression, such as hitting or pushing, is a common concern in school settings and can interfere with students’ academic engagement, peer relationships, and classroom participation.
While these behaviors are often addressed through behavior management systems, school-based speech-language pathologists (SLPs) play an important role in understanding the communication needs that may underlie them. In many cases, physical aggression reflects a breakdown in functional communication rather than intentional defiance. When students lack the language or alternative communication systems to express needs, behavior may become their primary means of communication. This blog explores how SLPs can address physical aggression by focusing on teaching functional communication as an evidence-based intervention.
What Is Functional Communication-Based Intervention?
Functional communication-based intervention is grounded in the idea that challenging behaviors often serve a communicative purpose. Students may engage in physical aggression to gain attention, escape tasks, obtain items, or express frustration. Functional Communication Training (FCT) is an evidence-based approach that teaches students an appropriate communication response that serves the same function as the behavior.
For example, a student who hits to gain attention may be taught to say “help me” or use a communication card. A student who engages in physical aggression to escape difficult tasks may be taught to request “break please.” By replacing behavior with communication, the student learns a more effective and socially appropriate way to meet their needs.
How School-Based SLPs Can Help
School-based SLPs support functional communication development through collaboration and targeted intervention. First, SLPs work with educational teams to identify the function of the behavior, often through a Functional Behavior Assessment (FBA). Once the communication need is identified, the SLP helps determine an appropriate replacement response based on the student’s language abilities, which may include spoken language, gestures, visual supports, or AAC.
SLPs also support implementation by embedding communication opportunities into daily classroom routines and therapy sessions. For instance, during structured activities, a student may be prompted to request help or a break instead of engaging in physical aggression. Consistent modeling, prompting, and reinforcement help strengthen the use of replacement communication across settings.
Conclusion
Physical aggression in schools is often related to unmet communication needs rather than isolated behavioral concerns. By focusing on functional communication, school-based SLPs can help students develop more effective ways to express themselves. Functional Communication Training provides an evidence-based framework for reducing challenging behaviors while improving meaningful communication skills. This approach supports both communication development and meaningful participation in the classroom.
